WATER-NOZZLE-FOR IM PACT WATER-WH EeLe-P SPECIFICATION formingpart ofLetters Patent No. 731,570, dated June 23, 1903.

Application filed April 8, 1902. Serial No. 101.863. (No model) To allwhom it mayconcern:

Be it known that I, GEORGE JI-HENRY, Jr., a citizen of the UnitedStates, residing in the city and county of San Francisco, State ofCalifornia, have invented certain new and useful Improvements inWater-Nozzles for Impact Water-Wheels; and I do hereby declare thefollowing to be a full, clear, and exact description of the same. IOThis invention relates toa certain newand useful water-nozzle for use inconnection with that class ofwater-wheels known as impact-wheels orthose propelled by a jet of water orimpact-stream ejected against a-se-I5 ries of impelling-buckets attached to the periphery of the wheel.

Theinvention also consists in certain means whereby the outlets of thenozzle maybe con-' trolled to vary the area of the discharged 2o streamsor to regulate the outlet-openings of the nozzle.

To comprehend the invention, reference should be had to the accompanyingsheets of drawings, wherein- Figure 1 is a side view in elevation,disclosing the invention as applied to a tangential water-wheeh'thecasing for the'wheel and nozzle being in section. Fig. 2 is a verticalsectional end view taken on line was of Fig 3o 1 of the drawings. Fig. 3is adetail end view' of the nozzle cut-off and its adjusting mech anism.Fig.4 is a top planview of the cut off bandtfor the nozzle. Fig.5isasectional view ofthe bandor plate. Fig. 6 is a detail 3 5 view of oneof the g'uidesfor the cut-off band f and Fig. 7 isa plan view of one ofthe. guides,

showing a portion of the cut-oif baud or'plate therein. t

In the drawings the numeral 1 is used to 40 indicate a casing or housingof any suitable typefor the water-wheel 2, located therein; which wheelissecured to the shaft 3, working through the casing. To the peripheryof this wheel issecured a series of water-buckets 4, preferencebeinggiven to the centrally-divided class of buckets.--

Within the housing-or casing 1 is arranged the watennoz'zle 5, which inthe present case completely encircles'the water-wheel 2. This is locateda distance from the water-wheel, so

place its openin s 10 in or out of as ,to give a clearance-space 6 forfree rotation of the wheel within. 7 V p The water-wheel nozzle isillustrated-as be ing formed integral with coupling-section 6', whichextends outside of the casing or housing and forms connection with thewater-line or en pply-pipe. (Not shown.)

The water-nozzle 5 is formed with a series of outlet openings 7,arranged an equidistance apart, each opening in the present case beingprovided with a nozzle-tip 8, through which the water escapes. By thisarrangement of a water-nozzle with a series ofoutletopeningsanumberofimpact-streamsorwaterjets are simultaneouslydischarged tangen- 6; tially against the buckets of the water-wheel.

In front of the outlets of the nozzle is located. aslide cut-0d 9,whichin the present case consists of a circular band. This cut-Oif 9 isprovided with a series of openings 10, which are designed to registerwith the outlets of the nozzle. The cut-off works within the guide- .wayformed by the flanges 11 of the plates 12 and the face of thenozzle-tips. However, any suitable form of guideway or support for theslide cut-0E may be utilized. To one portion ofthe slide cut-01f issecured the rack 13,

with whichmeshes a rack-pinion 14, attached- .toinner end portionofpross-rod 15. This [rod extends through thecasing or housing 1 and, issupported by uprights'1611'6. Toithe endof the rod 15, projectingbeyondsupport "16,,is attached a band-wheell'fifby means of which therod is turned toactuate the rackpinion, so as to operate theslidecut-01f to re y with the outlets of the nozzle, the nozzle tips whenused being considered a portion of the outlets of the nozzle 5. Bymeansof this cut-ofi mechanism the outlet-openings of the nozzle arecontrolled or regulated to increase or decrease the area. of theimpact-streams discharged therefrom onto the water-whom buckets. I

The water-nozzle may only partially'encir- 5 cle the water-wheel; but Iprefer to extend the same therearound. By 'so encircling the wheel theforce of the impact-streams is evenly distributed, thereby approximatelybalancin g the .wheel throughout its work.

Section 6' of the water-nozzle is provided with a controlling-gate (notshown) which is raised or lowered by mechanism 18 in order to admit orcut oflf the supply of water to said nozzle from the main-line pipe.

' Having thus described the invention, What is claimed as new, anddesired to be protected by Letters Patent, is-

In com bination with an impactwheel, a water-nozzle provided with aseries of outletopenings, a nozzle-tip for each outlet-opening, platessecured to the nozzle on opposite sides of the nozzle-tips andprojecting outwardly to a point beyond the discharge ends of said tips,

inwardly-turned flanges at the free ends of [5 the plates, and a cut-offslidable between said plates and between the flanges thereof and thedischarge ends of the nozzle-tips; substantially as and for the purposedescribed.

In witness whereof I have hereunto set my 20 hand.
